FIXTURE CALCULATOR
Our easy tool tells you how many lights you need & how far apart they should be installed.
Click the cube icon 
& enter the room's dimensions. "Workplane Height" is where the light levels will be measured from. For example, 2.5 ft is about desk height. "Suspension Length" is how far your fixture will hang below the ceiling. If the fixture will be flush with the ceiling or recessed, enter 0.
As you make changes, the layout updates instantly to show recommended fixture (luminaire) quantities and spacing. Click the printer icon 
in the top bar to get a report you can print or share.
